RD Web- The computer can’t verify the identity of the RD Gateway. It’s not safe to connect to servers that can’t be identified.

Are you getting the error code: “The computer computer can’t verify the identity of the RD Gateway. It’s not safe to connect to servers that can’t be identified”? You most likely setup Remote Desktop Web Access (RDweb) with a self signed certificated.

The reason why you are getting this error is your machine doesn’t trust and can’t verify the identity of the RD Gateway. To allow your machine to trust the RD Gateway and get RD Web Access working you will need to import the Cert from the website and put it into the “Trusted Root Certification Authorities” store .

On the error pop-up click the “View Certificate” button.

Click on the Details tab and then hit “Copy to File…” we will back the cert up to our desktop.

A Wizard will pop up. You will need to select the type of cert. Select “DER encoded”

Specify the location

The export should complete without errors.

Right click cert and select Install Certificate.

You are going to Place the cert into the “Trusted Root Certification Authorities” store. You will need to click “Browse” to select it.

The import should work,

You will be asked “Are you REALLY sure you want to install this cert.”. Yes… Yes you do.

You will be told the import was successful.

Close all browser. Go back to the RD Web Access URL and re-logon. Everything should work now.

Just look at the images 😉
I export the certificate to the desktop. Then when you are importing the freshly exported certificate you have to tell the program where that cert is otherwise how else will it know where it is?
